Mandevilla lindl plant named ‘SGred8’

ABSTRACT

The new and distinct  Mandevilla  plant named ‘SGred8’ has upright and vining plant habit, relatively small and glossy foliage, freely branching habit, freely flowering habit, and is in full flower (bloom) around Mother&#39;s Day.

BACKGROUND OF THE INVENTION

In May, 2007, to obtain this variety, a red-colored nameless variety of a culture line possessed by Applicant was crossbred with mixed pollens of nameless varieties of a culture line possessed by Applicant on a farm owned by Applicant in Yusui-cho, Aira-gun, Kagoshima, Japan.

In February, 2008, a plant was grown through the above crossbreeding and seeds from the plant were planted in a soil to grow (germinate) and then bloom. This planting was carried out with the expectation that some different plant varieties could be obtained.

In April, 2010, among several hundreds of the flowering plants obtained from the above planting, one individual plant was selected and a branch (stem) thereof was inserted in soil on the farm owned by Applicant in Yusui-cho, Aira-gun, Kagoshima, Japan, to grow (cutting, i.e., vegetative reproduction) and such a vegetative reproduction was repeated for propagation.

In August, 2011, the above culture was completed after ensuring uniformity and stability. The combination of characteristics as herein disclosed for ‘SGred8’ were firmly fixed and retained through successive generations of asexual reproduction. In other words, it was confirmed that the individual plant having extremely good-colored flowers, which was ‘SGred8’, could be obtained with uniformity and stability, and the above repetition was completed.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘SGred8’. These attributes in combination distinguish ‘SGred8’ as a new and distinct cultivar of Mandevilla plant:

-   -   1. Upright and vining plant habit.     -   2. Relatively small and glossy foliage.     -   3. Freely branching habit.     -   4. Freely flowering habit.     -   5. Being in full flower (bloom) around Mother's Day.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to Japan Horticulture Standard Color Chart, edited as the 2nd print, resale on Sep. 10, 1997, except where general terms of ordinary dictionary significance are used.
